In 2012, private equity investments touched USD 7.5 billion.
Global consultancy Ernst & Young said that PE activity in the country has been range bound with an average of USD 8.5 billion across 400 deals in each of the last four years.
"2013 witnessed total investment of USD 9.1 billion across 392 deals... mainly due to few big ticket transactions," it said.
Total number of deals were higher at 415 in 2012.
In terms of value, the top ten deals accounted for about 45 per cent of the total private equity investments made in 2013.
"The largest deal of the year was announced in the Telecom space - Qatar Endowment Fund's investment of USD 1.2 billion in Bharti Airtel. This is the second largest PE investment ever in India," Ernst & Young said in a statement.
Reflecting change in the deal mix, early stage/venture capital transactions made up for about 46 per cent of the overall count registered last year.
However, Ernst & Young said there has been slowdown in mid-market deal activities due to "macro-economic slowdown, regulatory issues, governance matters and slow capital investment cycle and exit issues from current investments".
All these led to investors being more cautious, greater deal scrutiny and longer deal processes, it noted.
"Domestic consumption remained the central investment theme with close to 50 per cent of the deals in sectors like retail and consumer, food and agriculture, healthcare, financial services and real estate," the statement said.
The highest number of PE deals last year were seen in the technology space at 80 followed by retail and consumer (50), healthcare (49) and financial services (45).
Meanwhile, new fund raising plans worth USD 5.1 billion were announced last year whereas the same stood at USD 10.2 billion in 2012.
From an economic growth and government policy standpoint, there are no significant changes expected until the new government assumes office at the Centre in May/June 2014, Ernst & Young said.
"And even if it does, private equity investors are likely to take a cautious approach to investing leading to moderate activity levels for six to eight months of the year.
"The key focus however has to be on investor returns and exits - Limited Partners (LPs) are closely and critically watching the PE industry's performance in India and the next year or two are likely to define the medium term fate of the Indian private equity industry," the statement said.
